Abstract: The image display apparatus and a video wall including the same according to an embodiment of the present disclosure includes: a panel including a plurality of light emitting diodes; a scan driver to output a scan signal; a data driver to output a data signal; and a controller to control the data driver, and the data driver includes a plurality of data driving integrated circuits, and the data driving integrated circuit includes a current source, a switch disposed between the current source and the light emitting diode, and a coupling compensator to output a compensation signal for compensating coupling noise caused based on turn-on or turn-off of the switch. Accordingly, luminance uniformity between the plurality of light emitting diodes may be maintained.

Abstract: The present disclosure relates to an image display apparatus and a video wall including the same. An image display apparatus according to an embodiment of the present disclosure includes: a panel including a plurality of light emitting diodes; and a driving controller configured to output a scan signal for each of a plurality of subframe periods, and output a data signal for displaying an image, to the plurality of light emitting diodes, and the driving controller is configured to divide at least some subframe periods among the plurality of subframe periods into a plurality of group periods, and separately drive the light emitting diodes during at least some periods among the plurality of group periods. Accordingly, luminance non-uniformity between a plurality of light emitting diodes may be reduced.
